"Enable built-in audio switcher filter" & Audio Context Menu - they are different things, they have nothing in common.

So you're saying those are intentional changes you've made to MPC-BE compared to MPC-HC?

I don't care so much about Audio menu, but there should be a way to completely disable the internal subtitle renderer from loading any subtitles, which also prevents it from being enabled via context menus or hotkeys during playback. In MPC-HC the "Auto-load subtitles" check-box has that function, but it doesn't seem to have been replaced anywhere in MPC-BE.

I don't care how it's work in MPC-HC. But - it's work in MPC-BE. If you uncheck "Auto-load subtitle" - there is no Menu with subtitle list. In popup menu you can show only sub-menu with Subtitle Options.

I'm glad there's an official thread here for MPC-BE. I already switched player from MPC-HC to MPC-BE. I like the icons / GUI very much! I hope you replace the default Subtitle Filter to xy-VSFilter. Thanks!

Why isn't there a public source repository so we can view individual changes?

The next three months, the source repository is not available for free access. After a time, we may make the transition from a closed cycle development to the open.
Personally for you, I can grant access because you always acted like a gentleman.

Is there a list of changes and bugfixes compared to MPC-HC?

At the present moment, the ChangeLog is available in Russian language only.

At the current stage of development, it is not included in our top-priority tasks. Maybe later...

Thanks for this, I really like that it's darker, less distracting then the old BE mod and putting the time counter on the status bar is a great idea.

One issue is preventing me from switching to it from BE 4360 is save window size and/or position is unreliable, works maybe 50% of the time. I like to watch in full window mode but half the time it's opening as a window with the same resolution of the video. Any chance for a fix?

Also a few requests:
- Use a wider font or bold for time so it's easier to read.
- Option to auto hide title bar, Splayer has this, and while frame only with no borders has some effect, it breaks save window size/position on old be mod and it's also nice to have access to the title bar on demand.
- Option to hide toolbars in window mode, could work just like fullscreen mode hiding.

EDIT:
- Love the seekbar preview feature. Nice touch there! But "Use the preview in the search"? How about something like "Show video preview on the seekbar" (or something similar)?
- MPC-HC's "Output" settings tab looks better.
- Any chance for a "Lite" version?
- Any chance to change the default subtitle rendering resolution to "Desktop"?
- Why doesn't the window auto-resizes to the video's resolution when you open a file? Changed defaults? How do I make it act like it did in MPC-HC?
- Program's icon looks great.
- "Logo" settings tab can be removed IMO.
